Methoxymethane (DME) is an organic compound with the chemical formula C2H6O. This colorless, flammable gaseous compound serves as a homologue of methyl ether and possesses excellent physicochemical properties that make it valuable for numerous industrial applications.
Methoxymethane appears as a colorless gas with a slight ether aroma at standard conditions. Key properties include:
Methoxymethane serves as an efficient, clean-burning fuel alternative with:
Its low boiling point (-24.9°C) makes it ideal for:
As a versatile intermediate, DME facilitates production of:
The predominant industrial method using the reaction:
Advantages include simple process flow and low production costs. Typical catalysts include γ-alumina and ion exchange resins.
Two process variations:
| Method | Reaction | Advantage |
|---|---|---|
| One-step | 2CO + 4H2 → CH3OCH3 + H2O | Direct conversion |
| Two-step | Syngas → Methanol → DME | Flexible feedstock |
